If you are unable to quickly find the DB, it is probably hiding in the "System Resources" tab of the project tree - below most of your every-day portal project tree items.  Expand that tab and look at the DBs in there.

Also, you can use the Cross References tab from WinCC tag list to find the PLC DB reference - assuming you are not using optimized DB reference.  Since you know the DB # in WinCC, it likely means that DB is not optimized and is being accessed using absolute addressing.

I only know the DB number from WinCC. I want to find this DB in the project on tia portal. The project is large. Is it possible to search only by the symbolic name of the DB? in picture doesn't find 1122 and DB1122
